I am not sure of myself so I hope noone minds that I ask some real basic things about constructing the PCB in Step 3 of the $50 Bot.

I have the DIP socket, 3X6, 3X5, and the 2X5 male header pins soldered in place. As I understand it of the 6 pins closest to DIP socket get attached to pins directly across from them on the socket one to one 23-28. The 5 pins closest to the DIP socket also get attached in the same manner one to one 2-6.

Q1 What is the manner of attachment, fill-in with solder, make small jumpers or what else did I not see in the picture?

Q2 The Programmer Head pins go to location across the board I am think I need jumper wires for them, do I tin them and attach them to the pins as called out?

Those aren't really failures, just incomplete boards...I take it all thats left is connecting the power buses?Overall it looks like an excellent board, all the soldering is very neat and tidy and the wiring is superb!

the easiest way that i found was to "tin" the empty pad then bridge it with solder...but the best way that i have found was to solder the pin directly next to the socket which requires no jumperingbut i guess its too late for that

You have lost me guess i do not get the power buses at all. I do not understand what I did not do. I looked this up on here and see it discussed but do not get it, sorry. I am thankful for your help and sorry to be so dense.

I think you might have just turned the light on! .I just need to fill in the red lines connectting the pins with solder from top to bottom in four places and this will complete my power buses? (WOW even sounds like I might understand!)

Please review the location of the three pin header. It matches the instructions pictorial but the instruction may indicate to move it one hole over? The input voltage is ok nowbut the regulated does not seem to be connected.

Your three pin header is just fine where it is, there are and should be only two connections to the header, ground and input voltage. One pin is left unconnected to make sure you place the connector the right way round. The regulated voltage only needs to be connected from the output out of the voltage regulator to the power buses, just the way you did it with the green wire.

Think I've spotted the problem, the way you've soldered in the 3 pin header, the center pin should be ground, and the pin on column E should be input voltage. In most 3-pin connectors the positive line is in the center, so it might be better to reconnect it so that input voltage is on the center pin and ground on one of the sides.

I could not have gotten this far with out all you guys helping me. To let you know that you have been teaching me something I found out what the problem was with the 5V power bus. The regulator was bad! got it replaced. I might have over heated it while soldering? So thanks again and see you in the programming section....
